10w Quartz Sleeve
For optimal performance, replace the quartz sleeve in your 10w Pondmaster Submersible Ultraviolet (UV) Clarifier
when you are unable to clean it completely.
A dirty sleeve will block UV light and reduce your clarifier's effective light spectrum.
Keep a spare handy and exchange it with a dirty one which can be cleaned later at your convenience. 8.75L
Also used in the Pondmaster 1000 PUV pressurized filter.
